Letters Patent No. 96,448, dated November 2, 1869.'v

IMPROVEMENT IN MACHINE FDR MAKING HOOPS.

The Schedule referred to in these Letters Patent and making partei thosame.

To all u'liom it may concern: Y

Be it known that l, WILLIAM LAWYER, of Macomb, in the county of St.Lawrence, and State ofNew York, have invented a new and usefulImprovement in Hoop- Maehines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof', which willenable others skilled in the -art to make and use the same, referencebeing had tothe accompanying draw ings, forming part of thisspccificat-imi.

This invention relates to a new and useful improvement in machines forfacilitating the manufacture of hoops, having particular reference 'towhat is called rackingf7 by those engaged .in the business, which meanssplitting with the grain ofthe wood, by means of pressure, the preparedwood; and

The invention consists in constrnetinga machine for this purpose, ashereinafter more fully described.

In the accompanying drawings- Figure 1 represents a top view.

Figure 2 is a side elevation of the machine, with parts broken away, inthe drawing, forthe purpose 0f showing the manner in which it isconstructed.

Similar letters of reference indicate corresponding parts. r

A represents the frame, which is made of wood, and of suitable size andheight for the purpose.

B B represent the sides of the machine, which are planks, of suitablewidth, secured to the inside ofthe partsrof the fl'auie.

U is an inclined bed, extending about one-half the length of the machinebetween sides B B', placed in grooves in the sides, and removable atwill.

D is an adjustable bar, also conlined in grooves in (he sides, so thatit may be moved back and forth.

E is the brake, or racking-lever, which has its fnlerum in the side Bplaced transversely across the flame, and works in a Vertical slot inthe side B'.

Its end extends out from the side, as seen in the drawing, and isconnected with the driving-lever F by means of the connecting-bars G.

H H are guidebars, which are placed in two pairs, so that they supportand guide the driving-lever, as seen in the drawing.

I is a spring, whichis attached vto the side B, and extends over themachine, and is 'connected with the lever l by the cord J, and serves toraise the drivinglever F, as well as the racking-lever E, after the samehave been forced downby the foot ot' the operator.

The timber for the hoop is split np into pieces of suitable size,sudicient to make, say from tive to twenty hoops, more or less,according as the timber may work lwhen split to the best advantage.

Then properly prepared,'one or more pieces are placed in the machine,over the bar D, with one end resting on the bed C. v

When thus placed, the racking-lever E is forced down on to it by meansofthe lever F.

The end of' the piece oftimber is first checked by splitting in a 'shortdistance, for as many-hoops as the ,piece is designed to make, when itis placed with its end under and near the racking-lever,"and the powervis applied. The strainl produced by subject-ing the timber to thepressure as it is f'ed along continues the checks connnenccd at the cud,and. in runningfthe piece through the machine, it. is sepa-rated orsplit with the grain of the wood into the number of' hoops firststarted. The-piece of timber thus being fed through the machine isscenin rcd color in the drawing.A

By placingr the. bed and the bar D above the racking-lever, an upwardaction of that lever will produce the same effect.

The guide and supporting-bars Hare connected with the frame A by meansofthe projecting.; arms K, and .they are so arranged that the lever 'Fmay be changed to the other end of the machine, so that it may be workedwith the left hand.

. The bed C and the barD may also bechangedv for lthe same purpose, asthe machine is constructed with that object in view.

The. bar'l) is madey adjustable for thepurpose of suiting the actionofthe racking-leverto the different kinds of timber, 'as tough orbrasil.

By the use of this machine, the operation-of rackl ing or manufacturinghoops is greatly facilitated.

Having thus described my invention, I claim as new, and desire to secureby Letters Patentt The combination of a bed, O, adjustable barD, a

racking-lever, E, and an actuating-lever, F, all ar` ranged andco-operating in the manner specified, to rack hoops. g

WILLIAM LAWYER.
